You create a simple free account, set up a channel and you are ready to broadcast live! You can choose audio or no audio. You can use a web cam or even your phone! It is also easy to share the link and embed it. Not only can you stream live, but you can record during the stream also. Check it out!
My mind has been spinning with all of the possible fantastic uses for this. You could broadcast an awards ceremony live, class play or anything really.
